Rentals/Temporary and Permanent Installation Tips:
By using a 1-1/2-inch spigot trap adapter and no-hub coupling, the ET117-008
may be removed and the standpipe left in its original condition. You can
unscrew the ET117-008 to check flow rates or re-install it at a new location
even if a trap adapter or wye and trap adapter combination are permanently
glued to the standpipe.
The two trap adapters provided with your ET117-008 will allow you to make a
connection to any standpipe configuration encountered: use the close 1/2-inch MIPT nipple in a threaded female fitting, the spigot adapter in a female
slip fitting, and a hub adapter over PVC pipe. The Beveled washer and O-ring
are interchangeable, but should not be used together.
No-Hub connectors:
Ideal for cast iron or non-threaded galvanized steel, Copper, and ABS/PVC
Pipe. With the use of non-hub Couplings, it is a simple procedure to splice
into any drain line to fabricate a standpipe.
Note:
In most residential applications, it is permissible to transition from metal to
plastic using no-hub couplings; however, some commercial buildings require
uniformity of materials throughout the drainage system, such as all no-hub
cast iron pipe. For this reason, it is advisable to determine the specific code
requirements for each job.

• The ET117-008 provides an air gap for all Schedule-40 DWV standpipes.
• These instructions are intended for a professional installer. Examples are
provided without giving details of every procedure.
The standpipe used with an ET117-XXX Series air-gaps must be trapped, vented and fabricated from a Schedule-40
Drain Waste and Vent material that has been approved in your area, such as: ABS, PVC, galvanized steel, copper,
or no-hub cast iron with an inside diameter of 1-1/2-inch or greater. This will ensure compliance with plumbing code
requirements.
Below are the three practical standpipe configurations:
